Onkyo 706, No Sound

[mu1166]

My Onkyo 706 has been working flawlessly since I got it until about 2 weeks ago. Now it has a really bad tendancy to drop sound. I have been HDMI with no problems up to it started acting up. With HDMI, the picture never has a problem, but the HDMI word on the receiver will sit there and flash. I have since hooked up a digital toslink cable to my DISH receiver and a coaxial digital cable to my dvd player and it still looses audio.

Sometimes it will loose audio instantly, other times it will wait 20-30 minutes and then all of a sudden, no audio. After that it may take anywhere from 5 to 45 minutes for it to come back on. I've tried changing setting, running linear PCM, different input sources, etc. Nothing seems to work quite right. After it comes back on after it's lost audio, then it will work for the rest of the time it is on.

Sorry for the long post, but does anyone have any suggestions on a possible fix for my problem? It's getting a bit annoying...

Thanks

Have you tried a different HDMI cable or different HDMI input?

Does this happen with satellite only, or with DVD as well? Hate to say it, but it might need service. You still under warranty?

It happens with any HDMI cable that I have tried (2 differenent ones from monoprice, 1 monster and a vizio HDMI cable), does not matter if it is the DVD player or the satellite box. I have tried all the different HDMI imputs. I thought it might be a handshaking problem with HDMI but it still looses audio even when I'm running with a digital cable. Toslink or coaxial doesn't make a difference either.

I am bitstreaming everything to the receiver.

Yeah, I am still under warranty. I have not called them yet and was seeing if anyone else was having or had this problem.

You tied different sources, tied different ports, tied different cables (but all the same in manufacture) what proves it’s not the cables? Have you tied a different receiver, if not what proved the cables are good?

Seems like a digital bad connection, a drop of bits ;)

I have 3 different brands of cables at home. Tried all 3 into different ports, rearranged the cables, etc. Sound drops when connected to receiver. When HDMI is connected directly to tv, the sound works perfect. No drops, etc.

When I hook a digital cable up to the receiver from the satellite and dvd, it still drops the sound. Which makes me think it's something with receiver.

Do HDMI cables just all of a sudden go bad? They have been working flawlessley for the last 3 months and then a couple weeks ago, the sound just starts acting up.

Ok my bad, if the cables work elsewhere I don't think it's a cable issue. Yes now believe it's the receiver or settings but unable to figure out why it works sometimes and not other times if a setting. A setting should work or not, but not here or there thing.

Tonight hasn't been to bad. Completely unplugged all the HDMI cables from the receiver. Seems to work better. Sound only dropped once for about 10 seconds and hasn't failed yet. Not that it's working like it should. Been using toslink and coaxial tonight with minimum problems.. Still don't understand why it would work great, and then all of a sudden, lets just work poorly... o well. More trouble shooting to come.

Have you tried to do an avr reset to default settings?

Have you tried to do an avr reset to default settings?

Yes, I reset the receiver multiple times. It never made any difference. The sound would still drop.

[disneyjoe7]

Short of returning unit for repair, or getting another avr to test with I'm out.

Sounds like you have hit a wall mu1166, and maybe it's time to call the dreaded Onkyo CS. I love Onkyo products, but their CS isn't always the best. Give em a shout though and see what they can do. Here is a link to their CS page.
